Android 21 is burdened with a compulsive need to feed that can only be controlled with constant fighting. But after she defeats one foe and finds that her hunger remains without another nearby, she loses control completely and decides to turn the person nearest to her into a delectable treat.
She is from Dragon Ball FighterZ. Main baddie in all three stories. She is a Bio-Android with all the DNA of all known races (minus the Kai's) so she can turn anyone into candy like Buu.
